One of the biggest things that can put people off the idea of using a VPN is that they slow down your internet. This is mainly because you are adding an extra leg to the journey your data must take to reach its destination (via the VPN server). These days good VPN services are very fast and if you connect to a server near to you, you will often get 90% or more of your raw internet connection speed.
When you connect to the internet, your IP address and system information are sent along with each packet. Those requests go through the DNS servers of your internet service provider and are routed to the domains they’re requesting. During that time, the government and network snoopers can spy on your connection and log the data you’re transferring.
For large-scale implementations, choose a hardware device such as a VPN concentrator or VPN-enabled network appliance. Hardware-based VPNs perform better for larger installations. Also, the security of a software-based VPN built on a host with an OS such as Windows, UNIX, or Linux depends on the underlying security of that OS. Thus, you must keep the OS patched as well as keep an eye on the VPN software.
It is possible for some background services to send information across that initial, unsecured connection before the VPN loads. To be fair, the risk is relatively minor for most usage profiles. If you're establishing a connection automatically to your corporate server, you will definitely want to check with your IT team about how they want you to set things up.
It does not matter if a VPN offers strict no logging policies. If it exists outside every major surveillance alliance, or offers lightening speeds. The minute it leaks your IP, everything goes to the garbage, as your private identity comes forward. Buffered VPN, despite being new, follows through on all its promises. The DNS leak test did not reveal our true location.
CyberGhost has been around since 2011 and has come out strongly as a supporter of "civil rights, a free society, and an uncensored Internet culture." We really liked how the company specifically showcases, on their Web site, how folks normally prevented from accessing such important services as Facebook and YouTube can bring those services into their lives via a VPN.
